Medical Forum / General / Dentistry / August 2006Can I Glue A Piece Back On A Crown ?
....it's porcelain (?), front tooth, large corner piece. What kind of glue / bond will be safe to use? Thanks > ....it's porcelain (?), front tooth, large corner piece. > What kind of glue / bond will be safe to use? > > Thanks In my experience, these repairs rarely hold up for long. Many of the porcelain repair materials used in the dental office require etching with hydrofluoric acid, which is very corrosive. I'm using a bonding agent that doesn't require HFl etching, called "Etch Free" by Parkell--it's used in conjunction with C&B Metabond. Not to be technical, but this is expensive stuff, and even then my results have been mixed. IOW, this ain't a do it yourself job, and it's likely if this is a crown it will need replacement. Now, if I misinterpret you and this is a bonded resin restoration, it's very easy to replace, but you can't glue it on--it would have to be re-done by your dentist.

I had a resin restoration chip a few years ago. I used cyanoacrylate glue (that is, Krazy Glue) after finding a research study in which it was used internally in a patient, which suggested it was safe. I was surprised to find it would not hold long - just a couple days, perhaps, if you're careful - enough that, with re-gluing, I didn't look ridiculous 'till I could see a dentist less than a week later; I had some event to go to in the interim, and couldn't bear looking like I did. Oh, and don't get your fingers stuck to your teeth! Using the stuff requires dexterity, which fortunately, I have! I wonder if the glue dentists use for crowns is a specialized kind of cyanoacrylate cement - it smells like it, and there are many kinds.

Problem is that they have significant solubility in the mouth, so they don't hold up. The problem with someone doing it in their own mouth (besides the fingers getting stuck!) is that if you get it almost but not quite in place it can alter the bite and turn into a bigger problem (though usually these misaligned pieces quickly fall off. Steve SignatureMark & Steven Bornfeld DDS http://www.dentaltwins.com Brooklyn, NY 718-258-5001 superglue disolves in water. Water is also the catalyst to make it set-up glueing porcelan with this material is not recomended. porcelain can be repaired but only by a dentist who is familiar and has good success with porcelain bonding.

I realize that it is not the answer you want, but unfortunately, no commercial glue bonds to the metal substructure. > ....it's porcelain (?), front tooth, large corner piece. > What kind of glue / bond will be safe to use? > > Thanks |
